A nap is still sleep
Sleeping in contact lenses is associated with a higher risk of eye infection, including occasional or unintended sleep. A CDC report describes serious corneal infections after sleeping in lenses. The cases illustrate possible harm, not the probability of infection for one individual nap.
Follow the specific wearing plan
Some lenses have prescribed overnight uses, but that does not make sleeping in any lens safe. Confirm whether your exact product and individual fitting plan allow it. Ordinary daily-wear lenses should be removed before sleep; do not infer permission from comfort or oxygen claims.
Make removal easy before resting
Our practical suggestion is to prepare glasses before an evening on the sofa, a flight or a shift-work rest. For reusable lenses, have the proper case and solution ready. A predictable routine is more useful than relying on remembering after you feel sleepy.
Respond to symptoms
If you develop pain, unusual redness, light sensitivity or blurred vision, remove the lenses and seek prompt eye-care advice. Do not use another night of wear to test whether symptoms disappear, and do not treat the problem with leftover prescription drops.
